Having Barrett’s esophagus puts you at an increased risk for developing a certain type of cancer, called esophageal adenocarcinoma. This is a type of cancer of the esophagus (a muscular tube that connects the throat to the stomach and is made of different layers). The risk of developing esophageal cancer due to Barrett’s esophagus is about 0.5% per year for each year you have Barrett’s esophagus. Usually, before cancer develops, precancerous cells are found in the Barrett’s tissue. Although the risk is small, it is important to talk to your doctor about your risk, and continue to have regular check-ups to monitor for precancerous cells.
